Programmed Cell Death Deregulation in BCR-ABL1-Negative Myeloproliferative Neoplasms
BCR-ABL1-negative myeloproliferative neoplasms are classically represented by primary myelofibrosis, polycythemia vera, and essential thrombocythemia. These entities are stem cell-derived clonal disorders characterized by hematopoietic progenitor autonomy or hypersensitivity to cytokines, most of them presenting mutations in Janus kinase 2 (JAK2), calreticulin (CALR), or myeloproliferative leukemia virus oncogene (MPL). Deregulation of pro- and antiapoptotic genes is also claimed as an important mechanism involved in cell resistance to cell death and accumulation of myeloid cells in myeloproliferative neoplasms. Apoptosis, as one of the best-characterized types of programmed cell death, has a clear role in hematopoiesis control. However, the exact pathways affected in BCR-ABL1-negative myeloproliferative neoplasms have not yet been fully clarified. This chapter will explore the modifications affecting programmed cell death pathways involved in myeloid proliferation and how these alterations might be exploited in single or combined targeted therapeutic strategies
Corporate Social Responsibility/Sustainability Reporting Among the Fortune Global 250: Greenwashing or Green Supply Chain?
The sustainability reporting efforts of MNCs who are members of the Fortune Global 250 (FG250) was investigated. The focus was on sustainability reporting by MNCs of supply chain impacts. The reporting of FG250 MNCs was examined to determine if greenwashing was occurring or whether MNCs had committed to operating a green supply chain. A mixed methodology was used consisting of quantitative analysis of twenty-five MNC CSR/sustainability reports which were randomly selected from the FG250 listing. Qualitative analysis using content analysis was also conducted on the reports. Both methodologies concentrated on the sustainability reporting of the selected MNCs in regard to their supply chain. Findings were mixed as there were great variations among the MNCs in their level of sustainability reporting about their supply chains. Some MNCs did not report on the activities of their supply chain at all (20%), the majority of the MNCs reported on their supply chain impacts at the value and goal level (48%), while the rest reported at the management approach level (32%). A majority of the sampled MNCs could be accused of greenwashing due to the lack of detailed quantitative information provided by the MNCs on the environmental impacts of their supply chai
Potential Prognostic Significance of Decreased Serum Levels of TRAIL after Acute Myocardial Infarction
BACKGROUND: Since soluble TRAIL exhibits anti-inflammatory and anti-atherosclerotic activities both in vitro and in animal models, this study was designed to assess the relationship between the serum levels of TRAIL and clinical outcomes in patients with acute myocardial infarction (AMI). METHODOLOGY/PRINCIPAL FINDINGS: Levels of TRAIL were measured by ELISA in serial serum samples obtained from 60 patients admitted for AMI, both during hospitalization and in a follow-up of 12 months, as well as in 60 healthy control subjects. Serum levels of TRAIL were significantly decreased in patients with AMI at baseline (within 24 hours from admission), compared with healthy controls, and showed a significant inverse correlation with a series of negative prognostic markers, such as CK, CK-MB and BNP. TRAIL serum levels progressively increased at discharge, but normalized only at 6-12 months after AMI. Of note, low TRAIL levels at the patient discharge were associated with increased incidence of cardiac death and heart failure in the 12-month follow-up, even after adjustment for demographic and clinical risk parameters (hazard ratio [HR] of 0.93 [95% CI, 0.89 to 0.97]; p = 0.001). CONCLUSIONS/SIGNIFICANCE: Although the number of patients studied was limited, our findings indicate for the first time that circulating TRAIL might represent an important predictor of cardiovascular events, independent of conventional risk markers

Energy Consumption Behaviour in Historical Churches
The historical buildings are being categorized under low thermal comfort because of their primary construction materials and their architecture, requiring a large volume of air to heat to achieve the human comfort levels required today. The existing problems within the historical churches are increasing, destroying not just the cultural heritage, but also affecting the health of people using the building, raising environmental concerns and pushing the occupants to find solutions for heating and ventilation of the spaces for reaching the minimum thermal comfort while, at the same time, carrying for the preservation of history. As the Energy Performance of Buildings (England and Wales) Regulations 2012 does not apply to protected buildings, due to their heritage, or to any buildings used as a place of worship, the case study church building of Saint Mary de Haura from Shoreham-by-Sea was chosen to be monitored closely using data loggers, measuring temperature and humidity for a year, after which the temperatures were assessed and compared with the actual thermal comfort standards CIBSE TM52 and CIBSE Guide A. The achieved results demonstrate that the church’s indoor environment is found most of the time cooler than minimum thermal standards accepted, which place the church in searching position for finding a solution to achieve at least the minimum indoor environment required
